For a given gas at 1 atm pressure, rms speed of the molecules is `200 m//s` at `127^(@)C`. At 2 atm pressure and at `227^(@)C`, the speed of the molecules will be :

80 m/s

100 m/s

`100 sqrt(5) m//s`

`80 sqrt5 m//s`

Text Solution

Verified by Experts

The correct Answer is:

We have `V_(rms)* propto sqrt(T)" ":. (200)/(V)= sqrt((273+127)/(273+227)) implies V=100sqrt(5) m"/"s`.
